So I got an SSD for my Mac Pro and it has been good so far. I was using Photoshop to make some changes on a panorama, its a .psb that is over 17 GB. I have set up Photoshop so that my scratch disks are all 4 mechanical drives, and I unchecked the SSD as a scratch disk. I tried using content aware fill on a part of the image and left for a while. When I got back on, it said Photoshop encountered a problem because the scratch disk was full. I have 4 2TB drives set up as scratch disks and it looks like Photoshop only used my SSD, which was never checked as active! I had 80GB available on the SSD and it got filled up. I need to get the project done soon but am a little worried about working on it anymore because I am afraid it might mess with the SSD. I have three questions. 1. How can I make this not happen again? 2. Where are the Photoshop temp files so I can delete them and get some space back? 3. I have an OWC SSD with the SF controller with garbage collection. Will this slow it down if I need to write something to it? And sorry if this is posted in the wrong forum, I just thought Mac Pro people would know Photoshop pretty well, especially since this pertains to having multiple internal drives. Thanks in advance for the help. EDIT: In Finder on the SSD, it now was that there is 58.51GB available. Every like 30 seconds to a minute, it will increase by about a GB. Is this because it is automatically deleting the temporary files? Wouldn't it be able to delete them much faster? Since it takes a while for a gig to show up, could it be because the SF garbage collection is kicking in and doing its sort of build in TRIM command on the drive?
